Posted by feww on February 18, 2017

January Third Warmest Recorded Globally

Arctic Sea Ice Extent. January sea ice extent was 8.6 percent below the 1981-2010 – the smallest January sea ice extent since satellite records began in 1979.

Antarctic Sea Ice Extent. January sea ice extent was 22.8 percent below the 1981-2010 – the smallest January sea ice extent on record.

Global Temperatures

The globally averaged temperature over land and ocean surfaces for January 2017 was 0.88°C (1.58°F) above the 20th century average of 12.0°C (53.6°F). This was the third highest January temperature in the 1880–2017 record, behind 2016 (highest) and 2007 (second highest).

Global land surface temperature was also third highest for the month of January at 1.54°C (2.77°F) above the 20th century average of 2.8°C (37.0°F).

For the oceans, the globally-averaged temperature departure of +0.65°C (+1.17°F) from the 20th century average was the second highest on record for January, behind 2016.

January 2016 temperature breaks 2007 record —NOAA

The January 2016 globally-averaged temperature across land and ocean surfaces (SST) was 1.04°C (1.87°F) above the 20th century average of 12.0°C (53.6°F), the highest for January in the 137-year period of record, breaking the previous record of 2007 by 0.16°C (0.29°F).

  • This departure from average is the second highest among all months on record. December 2015 was the highest at 1.11°C (2.00°F) above average.
    • These two months are the only two to-date to surpass a monthly temperature departure of 1°C.
  • January 2016 also marks the ninth consecutive month that the monthly temperature record has been broken and the 14th consecutive month (since December 2014) that the monthly global temperature ranked among the three warmest for its respective month.

The global land surface temperature was 1.56°C (2.81°F) above average, the second highest on record for January, behind only 2007.

  • Record warmth was observed across a swath of northern Siberia where temperatures rose at least 5°C (9°F) above the 1981–2010 monthly average.
  • Parts of southeastern Asia, southwestern Asia and the Middle East, most of southern Africa, and areas of Central and South America, and Nearly all of the South American continent were much warmer than average.
  • Northern Mexico, Scandinavia, and Central Asia around Mongolia were cooler than average, with a couple of areas that experienced much cooler-than-average temperatures, while parts of far western Russia and central Asia observed temperatures at least 5°C below average for the month.

SST

Record warmth was observed in all major ocean basins. The SST globally-averaged temperature departure of +0.86°C (+1.55°F) from the 20th century average was the highest on record for January, surpassing the previous record of 2010 by 0.25°C (0.45°F).
